Radar acquired data on subjects walking on a treadmill

Non-contact vital sign detection based on Doppler Radar systems has become widely utilized in healthcare applications, attracting significant interest and research over the past decade. Despite the existence of reliable wireless methods for detecting vital signs in stationary subjects, considerable attention is directed towards scenarios where the subject is in motion. To address gaps in the literature, radar data were collected from subjects walking on a treadmill. The data acquisition involved 15 subjects walking for an approximate total of 15 minutes each across four different experiments. The treadmill was positioned between two Continuous Wave radars, enabling the capture of data from both the front and the back of the subject. This paper describes the process of data acquisition, decoding, and the synchronization algorithm for ground-truth data, obtained from a system named BioPac.
